In trigonometric terms and diagrams, regular terminal angle rotation is anti-clockwise. This is to keep standards universal across all diagrams.

What is negative bearing?
a bearing is the angle from north moving clockwise 360 degrees a negative bearing is moving counterclockwise from north
What is the reference angle for -490 degrees?
When using autocad, 0 degrees was at 3 o' clock, then go anticlockwise for positive, clockwise for negative
If an angle measures over 90 degrees what is its complement?
obtuse angle * * * * * The complement of an angle greater than 90 degrees is not an obtuse angle! It would be a negative angle, whose measure would be 90 minus the angle whose complement you require. This would only make sense if the direction in which the angles were measured were fixed. For example bearings, which are always measured in the clockwise direction.
What is a rotation of symmetry?
Sometimes called rotation symmetry, or symmetry of rotation. If you have an object that can be turned through a certain angle (like rotating a cube through 90o) and then it looks identical, then that object has a certain symmetry under rotation. If you can turn it through any angle, like a cylinder, then it has rotation (or rotational) symmetry.
What a example of rotation?
A rotation turns a shape through an angle at a fixed point as for example if you turn around backwards that will be a rotation of 180 degrees.
What direction of rotation produces a negative measure of an angle?
Clockwise.
What does it mean when an angle is negative?
An angle is a measure of turn. the amount of turn is the magnitude, measured in degrees, and direction of turn can be clockwise or anti-clockwise. A positive angle turns in an anti-clockwise direction while a negative angle turns in a clockwise direction.
Why doesn't the direction of rotation clockwise and counterclockwise matter when the angle of rotation is 180?
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
What is a bearing in maths?
A bearing is a clockwise rotation from the North to the angle of the object.
Can reference angles be negative?
Certainly. A negative angle is simply clockwise instead of counterclockwise from the zero angle, but this is usually not indicated as such on a drawing.
What is the angle of rotation countr clockwise about the spinners center that maps label g to label b?
72
When is an angle positive?
An angle is positive when it is measured in a counter-clockwise direction. It is negative when it is measured in a clock-wise direction.
Positive and negative angles?
In the Cartesian plane, an angle is measured in the anti-clockwise direction from the x-axis. A negative angle is measured in the clockwise direction from the x-axis. However, an angle is effectively the same if you add or subtract 360 degrees. So, if you are faced with a negative angle just keep adding 360 degrees until you have a positive value.
6 -3 lies on the terminal arm of an angle The rotation angle to the hundredth in radians is?
9
What is negative bearing?
a bearing is the angle from north moving clockwise 360 degrees a negative bearing is moving counterclockwise from north
Is there a positive or a negative angle?
Yes. Angles may be measured from the direction of the positive horizontal axis and, clockwise is negative, anticlockwise is positive.
Why is Venus' rotation is about as long as Venus' year?
It is believed that Venus was struck by another large body. The angle of impact affected its rotation, which was likely similar to Earth and the other planets. Its counter-clockwise rotation was stopped and it now spins very, very slowly clockwise (east to west) as seen from the north.
